#define VCLStylesSkinPath "{localappdata}\VCLStylesSkin"

[Files]
;Install
Source: "VclStylesinno.dll"; DestDir: "{app}"; Flags: dontcopy
Source: "Styles\Auric.vsf"; DestDir: "{app}"; Flags: dontcopy
;Uninstall
Source: "VclStylesinno.dll"; DestDir: "{#VCLStylesSkinPath}"; Flags: uninsneveruninstall
Source: "Styles\Auric.vsf"; DestDir: "{#VCLStylesSkinPath}"; Flags: uninsneveruninstall

[Code]

{ Import the LoadVCLStyle function from VclStylesInno.DLL }
procedure LoadVCLStyle(VClStyleFile: String);
  external 'LoadVCLStyleA@files:VclStylesInno.dll stdcall setuponly';
procedure LoadVCLStyle_UnInstall(VClStyleFile: String);
  external '[email protected] stdcall uninstallonly';

{ Import the UnLoadVCLStyles function from VclStylesInno.DLL }
procedure UnLoadVCLStyles;
  external 'UnLoadVCLStyles@files:VclStylesInno.dll stdcall setuponly';
procedure UnLoadVCLStyles_UnInstall;
  external '[email protected] stdcall uninstallonly';

function InitializeUninstall: Boolean;
begin
  Result := True;
  LoadVCLStyle_UnInstall(ExpandConstant('Styles\Auric.vsf'));
end;

procedure DeinitializeUninstall();
begin
  UnLoadVCLStyles_UnInstall;
end;

推荐答案

您未指定VclStylesInno.dll的卸载副本的路径.

You are not specifying a path to the uninstall copy of the VclStylesInno.dll.

这是正确的方法:

procedure LoadVCLStyle_UnInstall(VClStyleFile: String); 
    external 'LoadVCLStyleA@{#VCLStylesSkinPath}\VclStylesInno.dll stdcall uninstallonly';

下次，只需遵循官方有关为Inno Setup卸载VCL样式的说明.

有关详细信息，甚至可能比官方解决方案更好的解决方案，另请参见加载外部DLL，以在Inno Setup中进行卸载过程.

For more details and maybe even a better solution than the official one, see also Load external DLL for uninstall process in Inno Setup.
